All of those who do not repent, and prepare their hearts for his return, see him return at their death. Behold, he comes with clouds; and every eye shall see him, and they also which pierced him: [the Jews and Romans] and all kindreds of the earth shall wail because of him. Even so, Amen. Rev 1:7 2000 years ago, to the Jewish High Priest and the Pharisees at his trial, Jesus said.. you will see the Son of Man sitting at the right hand of the Power, and coming on the clouds of heaven. Mark 14:62
Those not purified, to see Jesus’ return before death, see him as they die, as all peoples, all nations, all generations do. This is not a particular generation. Each generation has thought they were the special one to see a physical return.
This will not be a pleasant experience, particularly for those who thought that He would know them. At judgment, Jesus said he would reject many who called him Lord and had even performed miracles in his name by telling them plainly: ‘I never knew you. Away from me, you evildoers [they still sin]! Mat 7:21-23 Until we hear his voice, obey his voice, abide in his Him, and are purified by him; we still sin and he doesn’t know us. The foolish virgins without oil in their lamps, said: Lord, Lord, open to us. (without abiding in Him, his Light and Living Word, voice) Replying, Jesus said: Verily I say unto you, I know you not. Without abiding in Him, he doesn’t know us. Jesus knows listeners: My sheep hear My voice, and I know them, and they follow Me. John 10:27
